User Comments:
GUEST: I was updating my project from repository. The problem is my coleague committed changes to the project, he even changed type of the project from Java application to HTML5 project. After the update, I went to project properties and I have set the web and web-inf directories on the Sources tab. I think then the exception occured.

Either broken project.xml with no source-roots with "http://www.netbeans.org/ns/j2se-project/3" namespace or broken XML parser not handling namespaces. Be sure no XML Parser is on JDK endorsed classpath.

Better exception with project.xml content is now thrown.
